Joystick & Slider with Controller

As a proof of concept for the use of the RS-232 capability on our LCD controllers we recently made a small joystick, slider and button control board for our SVX-1920 controller (see picture), this connects to the controller RS-232 port. For this test we programmed the board for:

  • Picture in Picture (PiP): A single button press turns the PiP window on/off. The joystick moves the PiP window around and the slider adjusts the size of the PiP window. Another button selects different PiP modes.
  • On-screen markers: A single button hotkeys through various on-screen markers.
  • On-screen (OSD) menu: A single button turns the OSD menu on//off.

The idea behind this is to show a few of the ways that the RS-232 interface can be used to make a display much more than just a simple monitor by using some of the innovative features in Digital View controllers.

We will be putting this control board in a housing and also test with other other control presets for the buttons, slider and joystick. The SVX-1920 protocols for RS-232 are extensive so the range potential functions that this sort of interface board can be used with is considerable. Other Digital View controllers also support RS-232 so this capability is not limited to the SVX-1920. 

Update: Joystick_photo_2We added a housing as shown to make it easier to use the joystick for demonstration and testing.
